Definitions

  • the herein invention pertains to a transport and support means for heavy, high-temperature articles and to its manufacturing process.
  • the herein invention refers to a transport and support means for heavy, high-temperature articles which is particularly adapt for use on cooling benches, in extrusion moulding plants or in the casting of non-ferrous materials such as aluminium, glass, etc., in the heat treatment process of glass, ceramics, etc. or in the transport of hot silica sand for the "shell moulding" process in the electrometallurgical industry, as well as in the heat printing process of textiles or other materials.
  • transport and support means as used in the description and in the Patent Claim includes the loop belts used to transport extruded aluminum products from the extruder head or moulded glass from the mould, as well as to transport the aforementioned through the various production or working processes, to transport hot silica sand and to transport and support textiles and other materials in the heat printing processes, as well as pads, tubes and/or rollers as used on extruding benches or as spacers in the production of extruded aluminium products and in the heat-treatment process in the ceramic industry.
  • hot aluminium bars on coming out of the press extruder head, are collected on a number of benches which then transport the extruded items through the various production stages, such as cooling, stretching, etc., at right angles to the extruding direction. While the extruded product is transported away from the extruding head and transferred from one process stage to another the product gradually cools down from a typical initial temperature of approximately 550-600°C.
  • Each bench includes: two rollers, of which one is a drive roller, a support plate positioned between the two rollers and a conveyor belt placed around the rollers and plate which supports the extruded product.
  • this belt Given its role, there are many characteristics required of this belt some of which include: high temperature resistance, low heat transfer, high density to transport heavy and high-temperature products, good tracking, smooth surfaces so as not to cause pits or scratches on the surface of the hot extruded product, adequate friction coefficient as to avoid slipping on the pulleys, dimensional stability under the combined action of heat and pressure, reduced hygroscopic properties, slower cooling times at working temperatures, no released gas during heat decomposition, reduced or zero elongation to avoid slipping on the driven pulleys, etc.
  • the belts undergo high elongation thus causing sagging and side movement during running so that they will override the guide plates.
  • belts which consist of a support base or element made of one or more ply of polyester fabric. A cushion pad on non-woven fabric made of heat-resistant fibres is then glued onto the support. These belts are made tubular (endless) by sewing together both the support ends and the ends of the cushion pad.
  • conveyor belts which are made of a flexible fabric base made of fibres with a heat resistance of at least 150°C and a layer or veil of heat-resistant fibre quilted or needled to at least one surface of the support fabric.
  • the flexible base fabric and the fibre layer form a single body with the fibre layer on one side and the fabric base on the other side.
  • the base fabric side is preferably impregnated and covered with a heat resistant resin so as to increase the friction coefficient between the transport rollers and the conveyor belt.
  • the fabric base is weft woven using heat resistant fibre threads, such as e polyparaphenylenperephthalamide fibre, known on the market under the trade name Kevlar, and warp woven using polyester fibres.
  • the goal of the herein invention is to eliminate the above drawbacks.
  • the goal of the herein invention is to achieve a conveyor belt which is adapt to the aforementioned uses and which, apart from having the aforementioned characteristics of heat resistance, smooth surfaces, adequate friction coefficient, flexibility, has a high resistance and rigidity at right angles to the running direction so that it does not curl up owing to the pushing effect of the cooling, retracting material being transported.
  • the support base may be made of either a single wefts woven fabric, one or more ply, using rigid, synthetic monofilaments with a diameter between 0.1 and 1.0 mm and warp woven using parallel, twisted or braided synthetic multifilaments or, preferably, made of a number of fabrics, one or more ply, as aforementioned, overlaid and alternating with synthetic, staple-fibre veils, all needled together.
  • Any synthetic monofilament on the market with a heat resistance of above 150°C may be used for the wefts weave to produce the support fabric.
  • polyesters such as polyethylenterephthalate (PET), preferably high strength polyheteroheteroketonic (PEEK) and the polyamides. These products, in general, have a strength of at least 4.5 g/den and a stretching to breaking point of 5-20%.
  • the multifilaments should preferably be made of continuous staple automatic polyamides, known on the market under the trade names CONEX, NOMEX, KEVLAR, TWARON, used alone or bound together.
  • the support base may be a one or more ply seamless endless fabric or it may be an open-ended.
  • the number of monofilaments in the weft and multifilaments in the warp is nor critical and may vary within a wide range based on the required mechanical resistance.
  • the number of monofilaments will be between 5 and 20 per centimetre, based on the diameter of each fibre; the number of multifilaments (1,000 - 2,000 den) may vary between 10 and 30 centimetres.
  • the supporting fabric it is preferable for the supporting fabric not to be very compact so as to aid penetration of the veil (batt) fibres through the fabric weave during the needling process.
  • the number of fabric ply is not critical and depends on the required right angle rigidity. This generally varies between 1 and 5.
  • the synthetic, staple, heat-resistant fibres used to make the veil include both the aromatic polyamides, which are known under the trade name CONEX, NOMEX, KEVLAR, TWARON, and the polybenzimidazoles (PBI) made by the U.S. firm Celanese.
  • the transport and support means may be thermostabilised by pressurised heat treatment up to 200 kg/cm at a temperature of between 150°C and the maximum allowable temperature for the least heat resistant fibres.
  • transport and support means may be compacted in a steam or oil operated press heated to a temperature of 150 to 260°C at a pressure of between 5 and 50 kg/cm 2 .
  • transport and support means may be surface ground to obtain a smooth surface and even thickness.
  • the flexible support base for the conveyor belt pertaining to the herein invention may be made of at least one weft woven fabric (1), one or more ply (1a, 1b, 1c), using rigid, synthetic monofilaments with a diameter between 0.1 and 1.0 mm and warp woven using multifilaments (1d).
  • This fabric (1) is manufactured on a shuttle loom in both the endless and open-ended versions.
  • the fabric (1) may be used as such for the support base or, preferably, it may be used by overlaying and alternating layers of the fabric (1) with staple-fibre veils (4). Preferably, there should be from 2 to 4 overlaid layers.
  • Fig. 7 illustrates a support base made of two layers of fabric (1) and two layers of staple-fibre veil (4).
  • the support base made of alternating, overlaid layers of fabric (1) and staple-fibre veils (4), is achieved by feeding the fabric (1) from a roll (6) onto the stretching rollers (2a, 2b, 2c) and laying the staple-fibre veil (4) from a lapping machine (3) onto the fabric (1).
  • the rollers should be set at the distance required from the to the other to obtain the belt circumference required.
  • the fabric (1) and the staple-fibre veil (4) are wrapped around the rollers (2a, 2b, 2c) once or twice based on the mechanical resistance required, generally from 1 to 5 windings, preferably from 2 to 4.
  • the starting wrapping edge shall not coincided with the end edge but shall overlap it by 5 to 10 cm, to ensure the greatest belt tensile strength. Any possible excess thickness owing to the overlapping may be eliminated by successive grinding treatment on the finished belt.
  • the alternating, overlaid layers of fabric (1) and fibre veils (4) are then needled together using barbed needles in a process which is generally known as needling.
  • the overlaid layers of fabric (1) and fibre veil (4) are repeatedly fed under the needles of a needling machine.
  • This machine consists of a support plate (7) and a needle head plate (8) with vertical movement.
  • the barbed needles penetrate right through the fabric veil layer, hook the fibres and pull them through or partially through the veil (4) and the fabric (1) thus creating interwoven and interbound points or areas of fibres which are bound to the fabric (1).
  • the support base thus achieved made of the fabric (1) or the bound multi-layer, fabric-fibre veil, is then impregnated with silicon rubber or heat-resistant resin, so as to obtain a heat protection or insulating barrier to the monofilaments and to the multifilaments.
  • Impregnation is performed by immersion or by spreading.
  • the thickness of the silicon rubber or the resin may be between 0.1 and 3 mm.
  • silicone rubber products on the market are ELASTOSTIL E 50 and E 70 produced and sold by Wacker Chemie and type 3-7044 TEXTILE RTV, produced and sold by Dow Corning. After impregnation, the rubber or resin is vulcanised.
  • the belt After impregnation or vulcanisation, the belt is placed onto the stretching rollers (2a, 2b, 2c) and a further synthetic staple-fibre veil (4') is fed onto the exposed surface.
  • a further synthetic staple-fibre veil (4') is fed onto the exposed surface.
  • more than one carded veil, overlaid and crossed (4') shall be fed onto the belt.
  • the staple-fibre veil or veils (4') are consolidated so as to create a felt structure, completely bound to the support base and covered or impregnated with silicon rubber or resin by a further needling process.
  • the compactness and density of the fibre veil (4') depends on the number of needle strokes or runs through the bound material. The number of strokes generally varies between 800 and 3000 cm 2 .
  • the insulation offered by the fibre veil (4') increases with their compactness or density and thus by the number of stokes per square centimetre.
  • the needled belt (5) made of layers of fabric (1), the interlining veils (4) and the needled, compacted surface veil (4') is then removed from the stretching rollers (2a, 2b, 2c) and thermostabilised under tension.
  • Thermostabilisation may be performed on calenders fitted with diathermic oil heated cylinders (9) or by infrared panels (10).
  • the treatment temperature should be at least 150°C and up to the highest bearable temperature of the monofilaments or by the belts fibres; the tension may reach 200 kg/cm.
  • This thermofixing treatment eliminates any possible belt elongation or deformation under working conditions. Thermofixing is generally performed at a higher tension than the belt is exerted to under working conditions.
  • thermofixed belt (5) successively undergoes press compacting treatment is a heated plate press (11).
  • the compacting treatment is performed by running the belt (5), on rollers (12), through the press pressure plates (11) at set length at a time.
  • the pressure plate temperature is set between 150 and 260°C and the pressing pressure may vary between 5 and 50 kg/cm 2 .
  • This compacting treatment allows for an increase in the belt (6) density of 15 to 30% and, particularly, the compacted needled surface layer (4') thus increases the insulating protection that the layer offers the support fabric.
  • the increase in belt density reduces wear on the working surface, improves belt resistance to cuts and abrasions caused by the sharp edges of bars and maintains belt thickness longer, thus stopping the bars from rubbing against the sides of the support plate owing to a reduction in belt thickness.
  • the belt density may be further increased by applying, before the compacting treatment, a resin, cross-linking agent or heat-resistant fixer, for example the silicon resin emulsion SILRES MP 42 E as produced and sold by Wacker Chemie.
  • a resin, cross-linking agent or heat-resistant fixer for example the silicon resin emulsion SILRES MP 42 E as produced and sold by Wacker Chemie.
  • a final grinding treatment will eliminate any overlapping thickness and make the surface smoother.
  • the belts can be manufactured to the width required or, preferably, for economical reasons, they may be manufactured to the maximum width allowed by the needling machine, spreading machine, thermostabilising and pressing machine and then cut to the required width.
  • the pads can be produced by cutting the belts.
  • edges of the belts or pads may be, if required, heat welded or resin coated to avoid fraying.
  • the transport and support means pertaining to the herein invention may have numerous other potential applications; for example, to transport ceramic and glass products as well as other high temperature products such as silica sand in the electrometallurgy industry, or the fabric transfer-printing process.
